GitHub Terraform PR diagrams

Show architecture diagrams directly in Terraform pull requests

Infragr.am helps reviewers understand Terraform changes visually by generating architecture diagrams as part of the pull request workflow.

Review architecture impact before merge

Terraform diffs can hide architectural impact. A generated diagram helps reviewers see new public paths, moved resources, changed data dependencies, and affected zones before code lands.

  • Detect Terraform changes in pull requests
  • Generate diagrams for reviewer context
  • Reduce review time for structural infrastructure changes

Keep diagrams close to code review

When diagrams appear in the PR, teams do not need a separate meeting or manual documentation step to understand the proposed architecture.

  • Attach diagrams to GitHub PR comments
  • Use deterministic output for before-and-after comparison
  • Help security and platform teams review the same visual artifact

Frequently asked questions

Why add diagrams to Terraform PRs?

Architecture impact is often hard to see in HCL diffs. Diagrams give reviewers a faster way to understand what the change creates, moves, or exposes.

Does the PR integration replace code review?

No. It gives reviewers visual context so code review is faster and less dependent on manually reconstructing architecture from Terraform files.
